DESCRIPTION
The microwave motion sensor is a microwave moving object detector designed using the principle of Doppler radar. Unlike ordinary infrared detectors, microwave sensors detect the movement of objects by detecting microwaves reflected by the objects. The detection objects will not be limited to the human body, and there are many other things. The microwave sensor is not affected by the ambient temperature, has a long detection distance, and has high sensitivity. It is widely used in industrial, transportation, and civil devices, such as vehicle speed measurement, automatic doors, sensor lights, and reversing radar. Due to the universality of microwave sensor detection objects, in actual life applications, another sensor will be used for targeted detection. For example, the microwave sensor + infrared pyroelectric sensor can effectively judge whether someone passes by, will not be interfered by sunlight, clothing color, and will not react to other objects.
